2 Claims. (01. 36-353) This invention relates to a device for notching fabric, or the like.

An object of this invention is to provide a device for notching fabric, or" the like, said device having an improved cutter, and being provided with means to prevent the clogging thereof by the portions cut from the body of the fabric in In this connection, it will be understood that in notching fabrics, especially in the garment industry, for marking parts of the garments before they are sewn together, in order to guide the operator in stitching companion parts of the garment together, a multiplicity of parts are disposed one on top of the other in a pile which may be of considerable thickness, for example four to six inches, or more, in thickness. Pursuant to this object of the invention, the cutter is constructed so as to enable such a thick pile of fabric layers to be notched quickly and uniformly, as to the notches in each.

fabric layer, and without excessive effort.

Another object of this invention is to provide a cloth-notching device of simple construction which may be readily assembled and disassembled and which requires a minimum of maintenance for the proper operation thereof.

The above and other objects, features and ad-.

vantages of the invention will be fully understood 7 from the following description, considered in connection with the accompanying illustrative drawings.

In the drawings: Fig. 1 is a front elevation of the; improved notching device of the invention;

Fig. 2 is a side elevation of the cutter and its mounting plate; Fig. 3 is a bottom view of the cutter and mounting plate;

Fig. 4 is a sectional iew taken along the line l-4 of Fig. 2;

Fig. 5 is a bottom of the device;

Fig. 6 is a sectional view taken on line 66 of i Fig. 7 is a sectional view taken on the line 1-1 of Fig. 1; and

Fig. 8 is Fig.6. I

Referring to the drawings, the cloth-notching device Hi comprises the preferably rectangular base or cloth plate I2, the vertical tubular standard l4 mounted on said plate, the plunger or actuator I6 mounted for vertical reciprocation in said standard and provided with the cutter-l8,- the view of a portion of the base compression spring 20 coiled about said plunger;

a sectional view taken on line 8'8 of and the tubular operating member 22 con centrically disposed about the spring, the plunger,

and the standard, and having an operating'p'ortion or handle 24 to which the plungeris removably secured, all of said parts being formed. of aluminum, or steel, or other suitable material.

The base plate I2 is provided with the beveled end portion 28, adapted to readily slide'under a plurality of superposed layers of cloth, or the,

like, and with a substantiallyflat upper surface,

26 adapted to underlie and support said layers in flat, horizontal position under the .cutter. Said upper surface 26 is preferably grooved as indicated at 38 to provide a friction surface adapted to prevent the bottom layers of the ma*-:

terial from moving on the upper surfaceof said base plate during the notching operation. On its under-side, the base plate is provided with the recessed portion or seat 32, adapted to receive the metal retainer or set plate 34 provided with the pointed angular portion 361extending there from and underlying atriangular' aperture 38. in the base plate (as illustrated in Fig. 5), in which; aperture, a substantially triangular insert ;or bumper 40, preferably formed of rubber orother;

resilient non-metallic material, is disposed flush withsurface 26, said bumper being'therebyre tained in said aperture against dislodgement by the cutter is, on the downward thrust thereof;

Set plate 3G is secured, in seat 32, tothe underside of the base plate by. screws :12. The base plate is provided, on upper surface 26, with the; longitudinally grooved portion or guidewayg fl which extends from the end H5 thereof to the,

shoulder or stop 41 adjacent standard l4 v(see, An adjustable stop or gauge 48, pro-. vided with the slotted portion 50, is mounted for movement in said guideway longitudinally of the}.

Fig. 6).

base plate, said gauge being removably secured in'a predetermined position thereinby set-screw 52 threaded into the bore 54 in base plate' l2.,;

If desired, the base plate'may haveinscribed therein any suitable indicia,such as at356, to indicate notch sizes,. whereby, when-Lend v58 .01 gauge 18 is positioned in'guidewayM in align:

ment'with one ofxsaid indicationsya notch.-of predetermined depth will be cut by the cutter [8,; as hereinafter described. ii The gauge 48-Iiis pro-.

vided with the recessedportion .60 encompassing,

The standard is secured to base plate 12 by welding or by other suitable means, and is provided with the longitudinal slot 64, extending from the bottom thereof to a point adjacent the 7 top thereof, the cutter element l8 being reciprocably movable therein. The plunger l6 isprovided with the longitudinal slot 66, at the lower.

end thereof, in which is disposed the cutter plate .or shank 58, said plate being secured to the plunger by the counter-sunk screws 10 threaded intorbores 'H-in-the plunger. When the plunger. isrmounted within the. standard, the plate or shankfiflfistmovablelongitudinally; of the slot 64 therein: whereby the cutter is carried by the plunger betweenth-e: upright members 62- of the guide 148.

The-cutterr'lti is preferably formed" of hardened steehand; comprises the a-ngularly "related surfacestorwalls Hi and 16 forming a cutting head, saidiwalls having a; common front edge 18. As:

illustrated: irr-Fig; 3, the surfaces 14 and 16 di-- .vergerearwardly from front edge 78 and'are moreefiicient" cutting action by providing progressivelyvincreasing cutting action of the cutter on the'layersiof fabric; it is tobe'noted that the front-wedge I3 is inclined rearwardlyf and upwardlyfromthepointediend'84' (see Fig. 6. The.

said lower edges are: sharpened. to readily cut through a plurality of superposed layers of fabric, and due to the angularrelation of. said edges they cut av shaped'portion therefrom to provide V-- shaped notches therein. The lower. edge 86 of plate is: preferably also sharpenedwhereby the:

V shaped portions; cutfrom the fabric, are cut by said lower edge 86 to form two substantiaily.'\I- --sha1;ved portions which readily move upwardly of the cutter, as the cutter cuts downward ly through the layers; in spaces 88, between each of thesurfaces'lkand' 16 and the'plate 68, where-- by saidcutportions of fabriewill not clog the cut ter but willfravel upwardly and outwardly there-- from}. When thetdevice is to be used forrnotche ingfsoft "fabric; such? as for example dress fabrics or thezlike, the. lowersedgei8fi' of plate BS-need not besharpened-although it is. preferred. that said edgeabei-sharpenedtto act :asa cutter as just.de-- scribed. Thezsh'arpened edge .86 is, however, de-

sirable especially when the device is to be used for notching? hard: fabrics. After cutting through the layers of fabric,;.the point84 andsharpened edges 80 and 8Z"Wi11 strike resilient bumper whiclrpreventsthe'dullmg of said point and cut tingedges:

Thei plunger' lB-"is provided-at its upper end with-the. threaded portion 90 which threads into theiinternal bore :92 in knob or handle24 of the operatingmember, 22 whereby the plunger is re lcasabhr secured-therein; Itwill be understood.

The loweror cutting edges that knob 24 need not be fabricated in the illustrated shape but may be of any desired shape and construction, and that the surface of member 22 below knob 24 may be changed or eliminated entirely. The compression spring 20 is coiled about plunger [6 and bears against the operating knob 24 and the upper end of standard 14 whereby, when a downward pressure is applied to the knob, the plunger is moved downwardly" therebycarrying the cutter? l8: downwardly toward the base plate l2 against the bias of spring 20, the full compression of the spring acting to stop the downward thrust of the cutter, or. if desired, an auxiliary stop may be provided on the standard.

The notching device I0 may be readily assembled-by removingthe set plate 34 from the bottom of base [2 and by removing the resilient insent 40 from the aperture 38. Thereafter, the movable plunger 16 having the cutter attached thereto maybeinserted into standard 14' through the bottom of base plate I2, with the threaded portion being first inserted and the plunger being-.moved into the standard so that cutter plate 68 will be engaged in-the longitudinal slot 64- therein; Thereafter, the: bumper 4D is inserted inthe aperture 38- and the set plate 34 is secured in positiomby screws 42. Thespring 2 0 is positioned over that portion of plunger 16 which projects above'standard l4 and the operat-- ing -member 22 ispositioned over the free endof plunger l6, and the threaded portion 90 thereof is threadedinto-boreSZ of knob.24-. The guide-:- 48; is secured imposition. on baseplata i2 by; 1 screw 52;

To operate notching device 10, the material. to be notchedis assembledin superposed layers, allsthe front edges rthereof being. flush. Beveled end 2'8: is slipped under the bottom layer and; sincethe material is resilient, the layers will all be in flat horizontal disposition on surfacefid with 'theifiush front edges thereof 'abutting'the verticallgauge members-B2. To adjust the depth OfLthBIIlOtCI'l', the: gauge'dll sh'ouldbe pre-set as desired; it." being apparent that as the guidemembers 62 are moved' toward edge 46 ofithe: base "plate; the depth" of. the groove willxbe increased. Byrforcing. knob 24 downwardly. the cutterrisizthrustrapidly through the layers, the: v-shap'edi cut-portions being again. out by r the cutting edge of blade '68 whereby said cut-por tions are moved upwardly on both sidesiof the blade". through the. spaces. 88':

From the above descripti'omit Wilma-apparent thatlin providing: a: cutting: element inwhich the cutting surfaces diverge rearwardlygfronra common edge and? heini planes? intersecting: the vertical axis of the device, in which the cutting edges are inclined upwardly from the bottom point of said edge, in which said common-edgeds inclined rearwardl'y to lie in" a'plane which intersects the vertical axis of the device, and in which" anadditi'onal-cutting edge is provided inter, mediate .the.first mentioned cutting edges, there has" been provided an improved cutter well adapted toperform the objects herein, when incorporated in the simplified device of this. in.- vention.

While L-haver shown and described. the presently preferred embodiment ofmy invention it willbe,- understood that various changes in the: details= ofgconstruction and in the form'and arrangement of: parts may be made without dfiparting fromtheunderlying idea or principles;

of this invention within the scope of the appended claims.

I-laving thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A cutting element for a device for notching the edges of stacked pieces of sheet material comprising a laterally extending shank adapted for the attachment of the cutting element at one side end thereof to an actuating member and having front and bottom edges, angularly related cutting parts joined together in V-defining relation and connected to the front edge of the laterally extending shank, said cutting parts diverging rearwardly from the front edge of the shank and depending below the bottom edge of the shank, said cutting parts having cutting edges on their lower depending ends to out 01f portions from the edges of the stacked pieces of the sheet material, said shank having a cutting portion on its bottom edge and within the confines of the cutting edges of the angularly related cutting parts and elevated therefrom whereby to sever the cut-off portions of the sheet material, said angularly related cutting parts respectively defining open passages at the opposite sides of the shank whereby the severed 6 cut-off portions 01' the sheet material are directed upwardly and outwardly of said passages as the cutting element is used.

2. A cutting element as defined in claim 1 and said cutting edges on the depending ends of the angularly related cutting parts being upwardly and rearwardly inclined from the joined front edges of the cutting parts.
